[QUOTE="oldbear58, post: 362255, member: 3312"] I recently visited the main perique factory in Convent, Louisiana. One of the barrels I examined had tobacco with a strong ammonia scent. That tobacco was removed and aired out before being repacked for further fermenting and aging. When I tested my perique tobacco I get a high pH of 8.5 to 9.0 (ammonia is a bit higher than this). While I am not prepared to make any overarching statements it appears that the nicotine level of most (if not all) tobaccos depends on the pH, at pHs over 7.0 nicotine becomes "protinated" and is much more biologically reactive. At acidic levels the nicotine is more insoluble and less reactive. Cigars that are more fermented might be more basic (higher pH) and stronger; remember that a typical cigar can contain enough nicotine to kill 2 or 3 people if it were all available. An ammonia smell in tobacco might just mean you can expect a bigger "kick"; I like the sour aftertaste of perique and a few of the stronger burleys. Oldbear [/QUOTE]
